- 40 kVA transformer is not a phase converter. It is usable for three-phase step-up or three-phase-step-down voltage.
- The transformer is unsuitable for converting any frequency from 50 Hz to 60 Hz or 60 Hz to 50 Hz. It can function either input and output 50 hz or 60 hz frequency.
- Silicon Steel Sheet
New cold-rolled silicon steel sheet, 0.27mm, 0.30mm, 0.35mm of thickness, excellent performance.
- Terminal Block
High-quality terminal block, excellent temperature resistance, pressure resistance, and flame retardancy for small power. For high power, made of quality copper material, with good electrical conductivity, and high temperature resistance, not easy to burn out the equipment when a short circuit happens.
- Enameled Wires
H class enameled copper/aluminum wires, temperature resistance 180℃, winded tightly and uniformly, no insulating layer, high heat dissipation, service life ≥35 years.
- Bobbin
Made of nylon, high-temperature resistance, and great flame retardancy. The high-power transformer with a frameless design has ventilation slots between the coils for smooth air flows which reduces the temperature of the coils.
- Insulation Process
The 40 kVA isolation transformer adopts H-class vacuum-impregnated insulation, temperature resistance of 180°C, lower noise, better insulation, and anti-rust and anti-corrosion.
